On October 24 2013 Andreas Espinoza defended his thesis on Myocardial monitoring by epicardial ultrasonic transducers. Andreas Espinoza and co-workers have developed an ultrasonic system for attachment on the heart for continuous assessment of myocardial function during cardiac surgery. As the patients undergoing cardiac surgery are getting older, and the surgical treatment is increasingly complex, this risk for complications increase. Perioperative ischemia is an important predictor for adverse patient outcome. Echocardiographic assessment for early detection of myocardial ischemia is superior to ECG or hemodynamic monitoring, but is performed intermittently.

Rahul Prasanna Kumar, Fritz Albregtsen, Martin Reimers, Ole Jakob Elle and Bjørn Edwin, from The Intervention Centre and Institute of Informatics, won the 3rd prize for the “Inven2 Best Innovative Idea 2013” along with a cash prize of 10.000NOK. The winners were selected from competition among 84 ideas and inventions. The project is titled “Fast and user-friendly blood vessel segmentation method” and is part of Marie Curie EU project, IIIOS. The work is on a novel blood vessel segmentation method, which is shown to be much faster than commonly used techniques.See Inven2 for more info in Norwegian on the award.

Abstract: Wireless Sensor Networks (WSNs) consist of a number of nodes responsible for monitoring data and transmitting it to base stations. Power efficiency is an important issue in WSNs, because nodes are powered by batteries. An effective approach to improve the efficiency of WSNs is collaboration among nodes. In this thesis, we study the problem of applying rewriting logic for formal modeling and analysis of cooperative communication in terms of power consumption. Formal methods provide an abstract model of WSNs and can simulate and validate them, in spite of simulators which can not validate WSNs.
In their report receiving online publication in Nature Medicine, investigators Kyrre E. Emblem and Atle Bjørnerud from the Intervention Centre present a new paradigm in cancer diagnostics by Magnetic Resonance Imaging (MRI) coined as Vessel Architectural Imaging, exploiting an intriguing and overlooked hysteresis effect in perfusion MRI that reveals new knowledge of tumor vessel type and function. Preliminary data show improved microcirculation and oxygen concentrations combined with reduced vessel calibers in brain tumor patients (glioblastoma) receiving anti-angiogenic treatment and the extent of this response correlate with survival.

Professor Arne Skretting is one of the pioneers of Medical Physics in Norway. He has a special focus on imaging technologies and dosimetry. Professor Skretting has established, developed and created interest for imaging technologies in hospital settings. He has also focused on patient safety within radiology and nuclear medicine. His achievements and extraordinary working capacity combined with knowledgeable insight has given him a unique position in Medical Physics, among collegues, physicians, bio-engineers and radiographers through many decades. Professor Skretting has been a popular mentor for Master and PhD students beside his clinical work, and has a large portfolio of scientific publications that has given him a strong reputation as a top scientist. He also has a special interest in PET research, and is an instrumental person within the Norwegian PET community.

On June 17th 2013 Airazat M. Kazaryan defended his thesis "New minimally invasive techniques in the treatment of patients with lesions in the liver: laparoscopy and extracorporeal high intensity focused ultrasound".
Laparoscopic liver resection has shown classical advantages of minimally invasive surgery over the open counterpart. In spite of introduction in early 1990-s only few centres worldwide adapted laparoscopic liver resection to routine practice. It was due to considerable technical challenges and uncertainty about oncologic outcomes. Various ablative techniques have been developed last 2 decades in parallel with laparoscopy. High intensity focused ultrasound (HIFU) attracts special interests due to its fully non-invasive nature.
The main goal of this thesis was to estimate and develop new minimally invasive techniques in the treatment of patients with lesions in the liver: laparoscopic surgery and HIFU. Image from left: professor Bjørn Edwin, Per Kristian Hol MD, PhD, Airazat M. Kazaryan PhD and professor Erik Fosse.
The Intervention Centre and Section of Neuroradiology at the Department of Radiology have had the pleasure to host Masafumi Kanoto, MD PhD, from Yamagata University Hospital in Japan. Dr. Kanoto is neuro radiologist, and the purpose of his 6 months stay was to study neuroradiology at an active research institute in Scandinavia. During his stay in Oslo he has been active in neuroradiology work and participated in different research projects. The visit was funded by the Japan Scandinavian Radiological Society (www.jsrs.dk), a society founded in 1985 with the purpose to facilitate exchange of radiologists between Japan and Scandinavia, and to arrange joint biannual scientific meetings. In 2001 this meeting was held at Oslo University Hospital Rikshospitalet, and the next meting is to be arranged in Turku, Finland, June 2014.

Professor Erik Fosse has been appointed to Commander of The Royal Norwegian St.Olav's Order by H.M. the King. Professor Fosse has been recognized for his contributions in medicine and for the socoety. The decoration will take place at Fanehallen at Akerhus Castle in Oslo on June 14th 2013.
On February 14th 2013 professor Frode Lærum was given the Order of St.Olav awarded by HRH King Harald on December 2012. Professor Lærum was one of the founding fellows of The Intervention Centre in 1996. The Order was given for his contribution to medicine and health sevices in Norway. Internationally, professor Frode Lærum also founded the Moscow Centre which was a collaboration project between Faculty of Medicine at University of Oslo and leading Russian universities in Moscow. Colleagues from The Intervention Centre congratulates Frode Lærum with this great achievement. The Order was given to professor Lærum at a reception at Akershus Universty Hospital.
During Q4 in 2012 the number of patients treated at The Intervention Centre exceeded 10 000. The clinical procedures involving humans started in 1996, and has increased gradually over the last years. All clinical activities taking place at The Intervention Centre are part of protocol based research projects. All patient participation is complying with ethical guidelines and is based on informed and written conscent according to current laws and regulations for medical research. The patient figures show the Centre's unique position as a Clinical Research and Development Centre. In addition more than 1000 experimental non-human lab procedures has been performed at The Intervention Centre. Finally, the number of peer reviewed research papers in international journals has passed 400. For more detailed information about The Intervention Centre download the latest Annual Report from 2011.

A multiprofessional research team of radiologists, radiographers and physisists at The Intervention Centre and the Radiology Department at Oslo University Hospital have collaborated to test whether ultralow-dose CT can replace chest radiography. The remarkable results of a preliminary pilot study will be presented at this year's annual meeting of the Radiologial Society of North America (RSNA). Several factors as patient radiation dose, sensitivity and specificity for the various modalities, lab time etc. have been assessed. Three experienced radiologists evaluated the images, and a physisist calculated the radiation dose. The pilot study is mentioned in a professional internet community.
